Sudden cardiac death can be caused by many different defects and predicting it has for a long time been a very difficult task. When studying the cardiac physiology one observes the different electrical forces carried out by the atria and ventricles. These measurements are summarized in an electrocardiogram, ECG, diagram which indicates the depolarization and repolarization of chambers of the heart. With electrodes, the following can be observed by the ECG; the P wave, which represents the atrial depolarization (atrial contraction), the QRS-complex, which represents the ventricular de polarization (ventricular contraction) and lastly, the T-wave, representing the ventricular repolarization.
